Abstract

PROBLEM TO BE SOLVED: To provide a bathroom floor with improved design capable of preventing mold growth and odor development, and a construction method thereof.SOLUTION: A bathroom floor comprises a subfloor 8 and a bathroom floor sheet 1 applied to the subfloor 8 through an adhesive layer 6 containing a fungicide. An internal corner part formed by the side of the bathroom floor sheet 1 or the side of the adhesive layer 6 and the surface of the subfloor is coated with a sealant 7 having a width of 2 to 10 mm.

Description

  The present invention relates to a bathroom floor and a construction method thereof.

In recent years, renovation has been actively performed in houses such as detached houses and condominiums, health care facilities for the elderly, nursing care facilities, and hospitals.
In these buildings, not only rooms and corridors but also bathroom renovations are required. In particular, bathroom floors in old buildings are often tiled, making bathers slippery, and in winter, the surface temperature is low, causing heat shock.

  As means for solving such a problem, for example, a bathroom washroom floor as shown in Patent Document 1 has been proposed (see Patent Document 1).

This bathroom washroom floor is composed of a surface material provided on the base material, a cushion material provided between the base material and the surface material, and a seal portion for closing between the wall panel and the edge of the surface material. And.
Specifically, the bathroom washroom floor is provided with a surface material 30 having hardness such as FRP on the base material 11 formed of a hard material such as FRP, and foaming of urethane or the like is provided therebetween. A cushion material 20 such as a body is formed.
Further, a seal portion 50 is provided for the purpose of watertightly sealing between the wall panel 80 and the edge portion 32 of the surface material 30. The seal portion 50 is applied around the surface material 30 along a gap formed between the outer end portion of the surface material 30 and the wall panel 80.

JP 2010-248890 A

  In the above-described conventional bathroom washroom floor, when the width of the seal portion is narrow, water tightness may be insufficient, and water may enter from the gap between the side surface of the surface material and the wall panel. The water that has entered from the gap penetrates between the back surface of the surface material or the back surface of the cushion material and the surface of the base material, causing generation of soot and odor.

  On the other hand, when the width of the seal portion is increased in order to prevent water from entering, the exposed seal portion is conspicuous, which may impair the aesthetics of the bathroom and cause a decrease in design. Generally, the seal material constituting the seal portion shows a white or gray appearance, and therefore, the presence of the seal portion may be emphasized more than necessary if the color tone of the surface material is different.

When the width of the seal portion is limited to prevent the deterioration of the design property, the water tightness is also limited, and water easily enters the back surface of the surface material.
In addition, a conventional bathroom washroom floor generally uses a hard surface material such as FRP, and since such a surface material is not flexible, it is likely to be damaged without a certain thickness. . If the surface material is made thick in order to maintain the strength, the thickness of the seal portion in the gap between the surface material side surface and the wall panel also increases, so that it is difficult for water to reach the back surface of the surface material.

However, when a resin sheet is applied on top of the existing base, and the floor is renovated, the sheet is relatively thin so that the floor height after renovation does not become too high. Must be used. Further, by reducing the thickness, the flexibility of the sheet can be improved and the workability at the time of reforming can be improved.
In this case, since the depth of the gap formed between the seat side surface and the wall panel becomes shallow and the thickness of the seal portion filled in the gap becomes thin, the gap between the seat edge and the wall panel is reduced. The infiltrated water becomes relatively easy to reach the back of the sheet.
Moreover, when the thickness of the sheet used for the renovation is thin, the temperature of hot water applied to the front surface is easily transmitted to the back surface, and the temperature of the back surface of the sheet tends to be relatively high. For this reason, on the back side of the seat, conditions for generating soot are set by water entering from between the sheet edge and the wall panel and high temperature, so that the back of the bathroom seat is likely to generate and proliferate, and There is a problem that odor is likely to be generated.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a bathroom floor that can improve the design of the bathroom and prevent the generation of soot and odors, and a construction method thereof. To do.

  The bathroom floor according to the present invention is made in view of the above circumstances, and includes a base and a bathroom floor sheet constructed on the base via an adhesive layer, and the adhesive layer is It contains an antifungal agent, and a corner formed by the side surface of the bathroom floor sheet and the side surface of the adhesive layer and the base surface is covered with a sealing material, and the width of the sealing material is 2 to 10 mm. It is characterized by that.

  According to this structure, the bathroom floor which can improve the designability of a bathroom and can prevent generation | occurence | production of a soot and an odor can be provided.

  Moreover, it is preferable that the bathroom floor which concerns on this invention is further provided with a bathroom wall surface, and the clearance gap between the said bathroom wall surface and the bathroom floor sheet is filled with the sealing material.

  According to such a configuration, the watertightness can be further improved by filling the sealing material in the gap between the bathroom wall surface and the bathroom floor sheet.

  In addition, the bathroom floor according to the present invention further includes a bathroom wall surface, and a drainage channel is preferably formed by the bathroom wall surface, a sealing material that is spaced from the bathroom wall surface, and a base surface. .

  According to such a configuration, by constructing a bathroom floor sheet on the base, it is possible to effectively prevent the generation of soot and odor by forming a drainage channel and increasing the drying speed of the bathroom floor surface. it can.

  Moreover, as for the bathroom floor which concerns on this invention, it is preferable that the planar shape of the said floor sheet for bathrooms is a shape by which the corner | angular part was rounded off.

According to this structure, it can prevent that the corner | angular part of a bathroom sheet contacts a bather's leg | foot and the brush for cleaning, and a bathroom sheet peels from the said corner | angular part.
In addition, in this specification, a planar shape means the shape when the surface is seen from the perpendicular direction with respect to the surface of a floor sheet.

  The present invention also includes a step of applying an adhesive containing an antifungal agent on the base to form an adhesive layer, a step of constructing a bathroom floor sheet on the adhesive layer, and a bathroom floor. The construction method includes a step of filling a sealing material in a corner formed by the sheet side surface and the side surface of the adhesive layer and the base surface.

  According to this structure, it becomes possible to construct the said bathroom floor simply.

(Floor sheet for bathroom)
The bathroom floor sheet 1 is a member that is constructed on the base 8 of the bathroom and improves the design of the bathroom. Although it will not specifically limit as the floor sheet 1 for bathrooms, if it can construct on the base 8 of a bathroom, For example, resin-made sheets, such as a vinyl chloride resin and an olefin resin, are mentioned.
Moreover, the surface shape of the said floor sheet 1 for bathrooms is not specifically limited, For example, the shape which has a smooth shape and an unevenness | corrugation is mentioned. The shape having irregularities is preferable in that it has a so-called anti-slip property that can avoid the risk of the bather slipping and falling. In addition, by forming a flexible sheet such as a resin sheet, the bathroom floor sheet 1 can be reformed while leaving the existing base 8 formed of FRP or the like. It becomes.

  FIG. 3 is a plan view showing one example of a bathroom floor sheet 1 used for the bathroom floor of the present embodiment, and FIG. 4 is a plan view showing another example of the bathroom floor sheet 1. 3 and 4 show only a part of the plane of the bathroom floor sheet 1, and the actual bathroom floor sheet 1 has a unit 2U (three large protrusions arranged in parallel) shown in both figures. The arrangement pattern of one collective part) is repeatedly formed.

The bathroom floor sheet 1 of FIGS. 3 and 4 has the same configuration except for the arrangement pattern of the units 2U. Therefore, in describing each component of the bathroom floor sheet 1 exemplified in this embodiment, the description will be made mainly with reference to the bathroom floor sheet 1 of FIG.
FIG. 5 is an enlarged plan view of one unit.

  In this specification, the fact that a bather can hardly feel pain when a part of the body (such as a knee) of the bather rides is sometimes referred to as “pain-proof”.

As illustrated in FIGS. 3 and 4, the bathroom floor sheet 1 exemplified in the present embodiment includes a seat body 1 a and a plurality of large protrusions 2 that protrude upward from the surface of the seat body 1 a. Further, as shown in FIG. 5, the surface 2a of each large protrusion 2 is provided with a plurality of small protrusions 31 and 32 protruding upward from the surface 2a. 3 and 4, the small protrusions 31 and 32 are not shown. The plurality of small protrusions 31 and 32 may have the same shape and the same size, may have a three-dimensional similarity, or may have a different shape. The plurality of small protrusions 31 and 32 may be provided irregularly on the surface 2 a of the large protrusion 2, but regularly (for example, in a region of the entire surface 2 a of the large protrusion 2 or a part thereof) , Preferably at a predetermined interval).
As for the floor sheet 1 for bathrooms of this embodiment, the planar shape may be formed in the rectangular shape or polygonal shape like a floor tile, and may be formed in the elongate sheet | seat. The bathroom floor sheet 1 formed in a long shape is usually wound around a roll and stored and transported.

The sheet main body 1a is a basic member constituting the bathroom floor sheet 1 of the present embodiment, and the large protrusion 2 and the small protrusions 31 and 32 are formed on the surface of the sheet main body 1a.
Since the sheet body 1a can be easily stored and transported and can be easily carried into the bathroom at the time of construction, the sheet body 1a preferably has flexibility such that it can be wound on a roll. The seat body 1a preferably has a cushioning property in order to increase pain resistance, and further has a heat insulating property in order to increase heat sensation and warmth in the bathroom, and therefore preferably includes a foam layer. .
The sheet body 1a may be entirely formed of a foam layer, but has a non-foamed surface layer to form the large protrusions 2 and the small protrusions 31 and 32 that are not easily crushed on the surface of the sheet body 1a. Is preferred.

As shown in FIG. 5, one large protrusion 2 has a rectangular planar shape, but the ratio between the long side and the short side is not particularly limited. In the illustrated example, the long side of the large protrusion 2 is approximately three times as long as the short side. One unit 2U formed by juxtaposing three large protrusions 2 having such a ratio has a substantially square planar shape. The planar substantially square-shaped unit 2U is suitable for arranging it regularly.
Specific dimensions of the large protrusion 2 are, for example, a long side of 15 mm to 35 mm and a short side of 5 mm to 12 mm.

The shape of the surface 2a in the cross section of the large protrusion 2 is preferably an arc shape that swells upward. The large protrusion 2 having such an arc-shaped surface 2a is easily guided to the groove portion 4 when water adhering to the surface 2a falls along the arc-shaped inclined surface. However, the shape of the surface 2a in the cross section of the large protrusion 2 refers to the contour of the surface 2a of the large protrusion 2 excluding the small protrusion when the large protrusion 2 is cut along a straight line parallel to the short side.
The large protrusion 2 having the arc-shaped surface 2a has the highest center portion in the short side direction.
The protrusion height of the large protrusion 2 at the highest portion corresponds to the depth of the groove 4.

As shown in FIG. 5, a plurality of small protrusions 31 and 32 protrude from the surface 2 a of each large protrusion 2 at intervals.
The planar shape of each of the plurality of small protrusions 31 and 32 is not particularly limited, and examples thereof include a planar circular shape; a planar elliptical shape; a planar polygonal shape such as a planar rectangular shape, a planar triangular shape, and a planar hexagonal shape; Can be mentioned.

The protrusion height of the small protrusions 31 and 32 refers to a difference in height between the highest part of the small protrusions 31 and 32 and the surface of the large protrusion 2. When the protrusion heights of the plurality of small protrusions 31 and 32 are different, the protrusion height of the small protrusions 31 and 32 corresponds to the average value of the protrusion heights of the plurality of small protrusions 31 and 32. .
The protrusion height of the small protrusions 31 and 32 is preferably 0.09 mm to 0.20 mm, more preferably 0.10 mm to 0.15 mm, and still more preferably 0.11 mm to 0.14 mm.

The maximum width of the small protrusions 31 and 32 is the diameter when the small protrusions 31 and 32 have a planar circular shape, and the plane when the small protrusions 31 and 32 have a planar shape other than the planar circular shape. The maximum width of the shape. Further, when the maximum widths of the plurality of small protrusions 31 and 32 are different, the maximum width of the small protrusions 31 and 32 corresponds to the average value of the maximum widths of the plurality of small protrusions 31 and 32.
The maximum width in the planar shape of the small protrusions 31 and 32 is preferably 0.40 mm to 1.20 mm, more preferably 0.45 mm to 1.20 mm, and further preferably 0.45 mm to 1.05 mm. is there.

The interval between the small protrusions 31 and 32 is the length between the centers of gravity in the planar shape of the adjacent small protrusions 31 and 32. For example, when the small protrusions 31 and 32 have a planar circular shape, the length is obtained by connecting the centers of the adjacent small protrusions 31 and 32 with a straight line, and the small protrusions 31 and 32 have a planar shape other than the planar circular shape. In this case, it is a length obtained by connecting the center of gravity of the planar shape of the adjacent small protrusions 31 and 32 with a straight line, and when the small protrusions 31 and 32 are a mixture of a planar circular shape and other planar shapes, It is the length that connects the center and the center of gravity with a straight line. When the formation intervals of the small protrusions 31 and 32 are different, the formation interval of the small protrusions 31 and 32 corresponds to the average value thereof.
The interval between the plurality of small protrusions 31 and 32 is preferably 0.75 mm to 1.20 mm, more preferably 0.87 mm to 1.10 mm, and even more preferably more than 0.87 to 1.10 mm or less. It is.

  The bathroom floor sheet having such small protrusions 31 and 32 is excellent in slip resistance, pain resistance and antifouling property.

  The arrangement pattern of the plurality of small protrusions 31 and 32 is not particularly limited. For example, in the large protrusion 2 shown in FIGS. 4 and 5, a plurality of small protrusions 31 and 32 are regularly arranged in a plurality of rows and multiple stages. Since the plurality of small protrusions 31 and 32 are regularly arranged in multiple stages, the sole of the bather hits the small protrusions 31 and 32 almost uniformly, so that the bathroom floor sheet 1 excellent in slip resistance can be configured. .

The plurality of small protrusions 31 and 32 may be different in size and shape, or may be different in at least one of size and shape.
The bathroom floor sheet 1 illustrated in FIG. 5 has the same shape and different sizes, that is, two types of small protrusions 31 and 32 having a three-dimensional similarity are alternately arranged. Hereinafter, the two types of small protrusions 31 and 32 having a three-dimensional similarity may be referred to as a first small protrusion 31 and a second small protrusion 32, respectively.
However, there may be three or more small protrusions. Thus, by providing small protrusions having different sizes, the number of small protrusions that can come into contact with the complex unevenness on the sole of the bather is increased, and the bathroom floor sheet 1 having excellent slip resistance can be configured. .

The thickness of the bathroom floor sheet 1 is preferably 2 to 4 mm. When the thickness of the bathroom floor sheet 1 is less than 2 mm, the strength as a flooring material may be insufficient.
On the other hand, when the thickness of the floor sheet 1 for a bathroom is thicker than 4 mm, the flexibility is poor, and therefore, workability may be inferior when the construction is performed in a narrow bathroom. In addition, when the bathroom floor sheet 1 is constructed on the existing bathroom floor material during renovation, if the bathroom floor surface after renovation becomes too high, the bathroom door and the bathroom floor surface come into contact with each other. May interfere with the opening and closing of the door, and there is a risk of bathing by bathers due to steps on the floor.
By setting the thickness of the bathroom floor sheet 1 to 4 mm or less, fluctuations in the floor height after the renovation can be suppressed within a range that does not hinder, and the aesthetic appearance after the renovation can be maintained.

  Since the bathroom floor sheet 1 used in the present embodiment has the above-described configuration, it is excellent in slip resistance, makes it difficult for bathers to feel pain, and easily removes dirt. Moreover, it is easy to remove dirt using a brush or the like, and the bather does not feel pain. Furthermore, the water adhering to the surface of the large protrusion can be discharged from the groove through the recess. In such a bathroom floor sheet, since water does not remain on the surface of the large protrusion for a long time, it is possible to prevent adhesion of dirt and scale and generation of mold.

(Adhesive layer)
The adhesive layer 6 exists between the bathroom floor sheet 1 and the base 8, adheres the bathroom floor sheet 1 to the base 8, and contains an antifungal agent to prevent generation of soot and odor. It is a layer to prevent.

  The adhesive layer 6 is formed by applying an adhesive containing an antifungal agent to the back surface of the bathroom floor sheet 1 or the surface of the base 8, and constructing the bathroom floor sheet 1 on the base 8. Is formed by curing with time.

  The adhesive is not particularly limited as long as it contains an antifungal agent and can bond the base 8 and the floor sheet 1 for a bathroom. For example, an epoxy adhesive, a urethane adhesive, an acrylic Examples thereof include resin adhesives, polyvinyl acetate adhesives, urea resin adhesives, silicone adhesives, modified silicone adhesives, and rubber adhesives. Of these, epoxy adhesives are preferable in terms of excellent water resistance and adhesiveness.

  The adhesive layer 6 contains an antifungal agent. The antifungal agent is not particularly limited as long as generation of wrinkles can be prevented. For example, benzimidazole antifungal agent, dodecylguanidine hydrochloride, N- (fluorodichloromethylthio) -phthalimide, N-lauryl-β -Alanine etc. are mentioned. Of these, benzimidazole antifungal agents are preferred because of their excellent antifungal effect.

The content of the antifungal agent is preferably 0.01 to 0.30% by weight with respect to 100% by weight of the adhesive. It is more preferably 0.02 to 0.15% by weight, and further preferably 0.03 to 0.07% by weight.
If the content of the antifungal agent is too small, the antifungal effect may not be obtained. Moreover, since the antifungal effect is saturated when the content of the antifungal agent exceeds a certain amount, if the content of the antifungal agent is too large, the economical efficiency may be deteriorated.

  In addition to the components described above, the adhesive may appropriately contain additives such as plasticizers, antioxidants, preservatives, ultraviolet absorbers, viscosity modifiers, pigments, and solvents.

(Sealing material)
The sealing material 7 covers a corner formed by the side surface of the bathroom floor sheet 1 and the side surface of the adhesive layer and the surface of the base 8, and fixes the bathroom floor sheet 1 on the base 8, and It is a member that prevents water from entering between the base 8 and the bathroom floor sheet 1.

  Fig.6 (a) is a longitudinal cross-sectional enlarged view of the bathroom floor which concerns on this invention. In FIG. 6A, the corner 5 formed by the side surface 1b of the bathroom floor sheet and the side surface 6a of the adhesive layer 6 provided below and the base surface 8a is covered with the sealing material 7. In addition, a gap formed by the side surface 1b, the side surface 6a, the base surface 8a, and the bathroom wall surface 9 is filled with the sealing material 7. As shown in FIG. 6 (a), the bathroom floor sealing material 7 according to the present invention has the highest vertex 7f where the surface 7e is in contact with the bathroom wall surface 9, and the contact point 7g with the surface 1c of the bathroom floor sheet 1 is high. It is desirable to provide the lowest surface 7e so that the surface 7e is inclined from the apex 7f toward the contact 7g. By providing the surface 7e with an inclination, the water adhering to the wall surface 9 can be poured on the surface 1c of the bathroom floor sheet 1 along the inclination and drained effectively along the inclination of the bathroom floor surface.

As shown in FIG. 6A, the width 7L1 of the sealing material 7 is the distance between the corner corner portion 7b on the bathroom floor sheet 1 side of the lower surface 7a of the sealing material 7 and the corner corner portion 7c on the bathroom wall surface side. It is.
The sealing material 7 constituting the bathroom floor according to the present invention has a width 7L1 of 2 to 10 mm. When the width 7L1 is smaller than 2 mm, the watertightness becomes insufficient, and water enters between the base 8 and the adhesive layer 6 or between the adhesive layer 6 and the bathroom floor sheet 1 to cause drought. Odor is likely to occur.
On the other hand, if the width 7L1 exceeds 10 mm, the exposed portion of the surface 7e becomes too large and the sealing material 7 is conspicuous, which may impair the aesthetics of the bathroom and lower the design.
Therefore, the width 7L1 is preferably 3 to 8 mm.

The height 7H1 of the sealing material 7 is the distance between the base surface 8a and the apex 7f.
Although the said height 7H1 is suitably set according to the height of the floor sheet 1 for bathrooms to be constructed, it is preferable that it is 1-10 mm.
If the height 7H1 is too high, the area of the surface 7e exposed around the bathroom floor becomes large, so that the sealing material 7 is conspicuous, which may impair the aesthetics of the bathroom and reduce the design.
When the height 7H1 is too low, water tightness cannot be sufficiently exhibited, and water may enter through a gap formed between the bathroom floor sheet 1 and the wall surface 9, and soot and odor may be generated.
Moreover, as shown to Fig.6 (a), it is desirable that the said sealing material 7 is higher than the floor sheet 1 for bathrooms.
If the sealing material 7 is lower than the bathroom floor sheet 1, the surface 7e of the sealing material 7 cannot be inclined from the apex 7f toward the contact point 7g, and water tends to accumulate on the surface 7e. When water accumulates on the surface 7e, water easily enters between the base 8 and the bathroom floor sheet 1, so that there is a possibility that soot and odor may be generated. Further, as described later, the corner portion 7d of the upper surface of the sealing material 7 on the bathroom floor sheet 1 side cannot be configured to ride on the surface 1c of the bathroom floor sheet 1, and the bathroom floor sheet 1 There is a possibility that the effect of preventing the water from flowing in between the base 8 and the bathroom floor sheet 1 cannot be exhibited.
Further, the difference 7H2 between the height 7H1 and the height of the surface 1c of the bathroom floor sheet 1 is preferably 1 to 6 mm, and more preferably 2 to 4 mm.
If the height difference 7H2 is too large, the sealing material 7 applied around the bathroom floor surface is conspicuous, which may impair the aesthetics of the bathroom and lower the design.
If the height difference 7H2 is too small, water may remain on the sealing material 7 and water may easily enter between the base 8 and the bathroom floor sheet 1.

As shown in FIG. 6A, it is preferable that the corner 7 d of the upper surface of the sealing material 7 on the bathroom floor sheet 1 side is placed on the surface 1 c of the bathroom floor sheet 1. According to this structure, since the edge part of the surface 1c is sealed by the corner | angular corner part 7d of the sealing material 7, it can prevent the upward dripping of the floor sheet 1 for bathrooms, and also the base 8 and bathroom use It is possible to more effectively prevent water from entering the floor sheet 1.
Further, the riding width 7L2 on the surface 1c of the corner portion 7d is such that the contact point 7g between the surface 7e of the sealing material 7 and the surface 1c of the bathroom floor sheet 1, and the corner 1e on the bathroom floor sheet 1 It is expressed by the distance.
The raised width 7L2 is preferably 0.1 to 1.0 mm.
If the raised width 7L2 is too small, the bathroom floor sheet 1 may not sufficiently exhibit the dripping prevention effect and the water entry prevention effect.
On the other hand, if the raised width 7L2 is too large, the sealing material is conspicuous, which may impair the aesthetics of the bathroom and lower the design.
Here, the construction method of the sealing material 7 will be schematically described. As described above, when the corner 7d of the sealing material 7 is on the surface 1c of the bathroom floor sheet 1, the width of the corner 7d is small, so that a masking tape is applied on the surface 1c. And the method of forming by apply | coating the sealing material 7 can be used suitably. The masking tape is affixed on the surface 1c except for the portion where the corners 7d are placed before the sealing material 7 is applied, and is peeled off after the sealing material 7 is applied.
In the above construction method, if the above-described raised width 7L2 is too large, the end portion of the sealing material 7 after the stripping removal that has been in contact with the end portion of the masking tape protrudes upward in the peeling direction of the masking tape. ) May occur.
When such protrusions are generated, not only the beauty of the bathroom floor is impaired, but also the protrusions stop the flow of water, so that water tends to accumulate on the surface 7e of the sealing material 7. If water accumulates on the surface 7e, water may easily enter between the base 8 and the bathroom floor sheet 1, which may cause soot and odor.
Further, when the bather's feet, a cleaning brush, a sponge, or the like comes into contact with the protrusions, the sealing material 7 may be easily drowned.
Further, when the resin forming the sealing material 7 is hard, the protrusions are also hard, so that there is a risk of feeling pain when the bather steps on the resin. Moreover, even when the resin is soft, there is a risk of causing discomfort on the soles of the feet when the bather steps on.

The sealing material 7 can be applied to the corner portion 5 shown in FIG. 6A, and is not particularly limited as long as the corner portion 5 can be prevented from being watertight. For example, a one-component silicone sealing material is used. Material, one-component modified silicone sealant, two-component silicone sealant, two-component modified silicone sealant, two-component epoxy sealant, two-component polysulfide sealant, one-component polyurethane sealant Materials, two-component polyurethane sealing materials, and the like.
Especially, the point which is excellent in scratch resistance and durability, the point which is excellent in adhesiveness with the said bathroom floor sheet 1, when the bathroom floor sheet 1 is formed with the soft vinyl chloride resin, FRP, mortar, stainless steel, etc. The one-component modified silicone sealant, the two-component modified silicone sealant, and the two-component epoxy sealant are preferable in that they can be applied on various bases of the above and are difficult to peel off after the application.

  It is preferable that the sealing material 7 contains an antifungal agent in that the sealing material 7 can be prevented from being soiled due to generation of wrinkles. As the antifungal agent, the same antifungal agents contained in the adhesive layer described above can be used.

The shape of the surface 7e of the sealing material 7 is not particularly limited, but is preferably a flat surface as shown in FIG. When the shape of the surface 7e is flat, it becomes difficult to stay on the surface 7e when water placed on the sealing material 7 flows along the slope, and when dirt on the surface of the sealing material 7 adheres, a brush or sponge It can be easily removed with a cleaning tool.
Further, the surface 7e is not limited to a flat surface, and may have a shape that rises in a cross-sectional view as shown in FIG. 6 (b), or as shown in FIG. 6 (c). The shape may be recessed in the direction. When the sealing material 7 has a raised shape or a recessed shape, it is preferable to keep the unevenness of the surface 7e so that water does not stay on the surface 7e and can be contacted by a cleaning tool.

(Base)
The base 8 is a member on which the bathroom floor sheet 1 is constructed via the adhesive layer 6. The base 8 is not particularly limited as long as it can be used for a bathroom base, and examples thereof include a mortar base, a concrete base, an FRP base, a tiled base, and a ceramic base.

  Hereinafter, a method for constructing a bathroom floor will be described. The bathroom floor construction method of the present embodiment includes a step of applying an adhesive containing an antifungal agent on the base 8 to form an adhesive layer 6, and a bathroom floor sheet 1 on the adhesive layer 6. And a step of filling the sealing material 7 in the corner 5 formed by the side surface of the bathroom floor sheet 1 and the side surface of the adhesive layer 6 and the base surface 8a.

  First, an adhesive containing an antifungal agent is applied on the base 8. The method for applying the adhesive is not particularly limited, and a conventionally known method can be used. For example, a method of flowing an adhesive on the base 8 and spreading it on the base 8 using an adhesive applicator such as a comb brush can be used. Thereby, the adhesive layer 6 is formed on the base 8.

  Next, the floor sheet 1 for bathroom, which has been cut in advance so that the width 7L1 of the sealing material 7 is in a desired range, is applied on the adhesive layer 6 before the adhesive is solidified. The applied bathroom floor sheet 1 is bonded to the base 8 via the adhesive layer 6 when the adhesive is solidified over time. Thereby, the corner 5 is formed with the width 7L1 by the side surface 1b of the bathroom floor sheet 1, the side surface 6a of the adhesive layer 6, and the base surface 8a.

  Next, the sealing material 7 is filled in the corner portion 5 formed in this way. The method for filling the sealing material 7 in the corner 5 is not particularly limited, and a conventionally known method can be used. For example, a cartridge filled with a paste-like sealing material 7 and having a nozzle at the tip is prepared, and the nozzle is moved along the corners while discharging the sealing material 7 from the nozzle at the tip of the cartridge. The method of apply | coating 7 so that height 7H1 may become desired height is mentioned. At this time, the shape of the surface 7e of the sealing material 7 becomes a flat surface, and the corner corner portion 7d on the bathroom floor sheet 1 side on the upper surface of the sealing material 7 is filled so as to be placed on the surface 1c of the bathroom floor sheet 1. preferable

After filling the corner material 7b with the sealing material 7, the sealing is completed by curing with time while maintaining the shape at the time of filling.
The bathroom floor is completed by the construction method described above.

  In addition, the construction method of this invention may have the process of shaping the sealing material 7 with which the corner 5 was filled further. The method for shaping the sealing material 7 is not particularly limited, and a conventionally known method can be used. For example, a method of smoothing the surface of the sealing material 7 using a tool such as a spatula can be used. By this step, the shape of the surface 7e of the sealing material 7 is adjusted, and the height 7H1 can be easily set to a desired height. In addition, the shape of the surface 7e of the sealing material 7 is flat, and it is easy to form the corner portion 7d with a width of 7L2 on the surface 1c of the bathroom floor sheet 1, and the aesthetics of the bathroom is improved. Since it can be made, it is excellent in design property.

According to the bathroom floor and the construction method described above, the base 8 and the bathroom floor sheet 1 constructed on the foundation 8 via the adhesive layer 6 are provided, and the side surface and the adhesive of the bathroom floor sheet 1 are provided. Since the corners formed by the side surfaces of the agent layer 6 and the base surface are covered with the sealing material 7, it is excellent in water tightness and can prevent water from entering the back surface of the bathroom floor sheet 1. It becomes. Since the width of the sealing material 7 is 2 to 10 mm, both watertightness and design of the bathroom floor can be achieved.
Moreover, since the said adhesive bond layer 6 contains an antifungal agent, generation | occurrence | production of a soot and an odor can be prevented effectively. In addition, in the bathroom floor and the construction method described above, since watertightness is maintained, even if water enters, the amount is small, so generation of soot and odor can be prevented.

The bathroom floor of the present invention has an adhesive layer 6 containing an antifungal agent, the side surface 6a of the adhesive layer 6, the side surface 1b of the bathroom floor sheet 1 provided on the side surface, and the base surface 8a. Since the corner 5 formed by is covered with a sealing material having a width of 2 to 10 mm, it is necessary for the bathroom floor to have excellent water-tightness, excellent design of the bathroom floor surface, and prevent wrinkles and odors. All three effects can be achieved.
Moreover, when the floor sheet 1 for bathrooms, such as resin with thin thickness, is constructed on the foundation | substrate 8, the said effect becomes especially remarkable.

Moreover, the sealing material 7 which has elasticity is filled in the clearance gap between the bathroom wall surface 9 and the side surface 6a of the adhesive layer 6 and the side surface 1b of the bathroom floor sheet 1 provided thereon, thereby further improving water tightness. Can be made.
When a resin sheet is used as the bathroom floor sheet 1, the bathroom floor sheet 1 may extend in the plane direction due to the heat of hot water, and may shrink in the plane direction due to contraction when the temperature decreases.
Even in such a case, if the filled sealing material 7 has elasticity, the dimensional change is absorbed, and no gap is generated between the bathroom floor sheet 1 and the sealing material 9. Water can be effectively prevented from entering.
In particular, when a modified silicone sealant is used as the sealant 7, the above effect is remarkable because it exhibits high elasticity and flexibility.

  FIG. 7 shows a second embodiment of the bathroom floor of the present invention. In said 1st Embodiment, although the bathroom wall surface 9 was provided and the clearance gap between the said bathroom wall surface 9 and the bathroom floor sheet 1 was shown with the sealing material 7, the sealing material was shown in this embodiment. 7 is different from the first embodiment.

FIG. 7 is an enlarged longitudinal sectional view of a second embodiment of the bathroom floor according to the present invention. In this embodiment, the width 7L1 of the sealing material 7 is such that, as shown in FIG. 7 (a), the corner 7b on the bathroom floor sheet 1 side of the lower surface 7a of the sealing material 7 and the corner on the bathroom wall surface side. It is the distance from (hem) 7c.
In the present embodiment, the range of the width 7L1 is the same as that of the first embodiment described above. For this reason, also in the present embodiment, the bathroom floor of the present invention can improve the design of the bathroom and is excellent in water tightness as in the first embodiment, and can prevent generation of soot and odor. The effect that can be produced.

In the bathroom floor of this embodiment, as shown in FIG. 7A, a drainage channel 10 is formed by a bathroom wall surface 9, a sealing material 7 constructed away from the bathroom wall surface 9, and a base surface 8 a. It becomes the composition.
By adopting the above configuration, the drainage channel 10 can be easily formed by simply constructing the bathroom floor sheet 1 on the bathroom floor, and the drying speed of the bathroom floor can be increased. It can be effectively prevented.

The width 10L of the drainage channel 10 shown in FIG. 7A is formed by the bottom 7c (10a) of the sealing material 7 on the drainage channel 10 side, the bathroom wall surface 9 and the base 8 in the longitudinal sectional view of the bathroom floor. This is the distance from the corner 10b.
The width 10L is preferably 10 to 50 mm, and more preferably 20 to 40 mm.
If the width 10L is too wide, water droplets are formed in the drainage channel 10 and there is a possibility that water does not flow easily. If the width 10L is too narrow, the capacity of the water in the drainage channel 10 is reduced, and the function as the drainage channel cannot be fully exhibited, and it is difficult to remove the dirt adhering to the drainage channel by cleaning. There is.

The height of the sealing material 7 of the present embodiment shown in FIG. 7 (a), that is, the height 10H of the drainage channel 10 is the top 7f of the sealing material 7 and the base 8 in the longitudinal sectional view of the bathroom floor. This is the distance from the surface 8a.
The height 10H is preferably 1 to 10 mm, and more preferably 2 to 4 mm.
If the height 10H is too high, the sealing material 7 exposed around the bathroom floor is conspicuous, there is a risk of deteriorating the design of the bathroom, and dirt attached to the drainage channel. It may be difficult to remove by cleaning.
If the height 10H is too low, water tightness cannot be sufficiently exhibited, and water may enter from the gap formed between the bathroom floor sheet 1 and the wall surface 9, and soot and odor may be generated. Moreover, since the water capacity of the drainage channel 10 is reduced and the water overflows at a slight flow rate, the function as the drainage channel may not be sufficiently exhibited.

7A, the height 7H1 of the sealing material 7 is higher than the combined height of the adhesive layer 6 and the bathroom floor sheet 1, so that the bathroom floor sheet on the top surface of the sealing material 7 is used. It is desirable that the corner portion 7d on the one side is placed on the surface 1c of the bathroom floor sheet 1.
By adopting such a configuration, the end of the bathroom floor sheet 1 is prevented from rolling upward, and water intrusion between the base 8 and the bathroom floor sheet 1 is more effectively prevented. The effect of doing can be demonstrated.
Furthermore, the difference 7H2 between the height 7H1 and the height of the surface 1c of the bathroom floor sheet 1 is preferably 1 to 4 mm, and more preferably 2 to 3 mm in the present embodiment.
If the height difference 7H2 is too large, the sealing material 7 applied around the bathroom floor may be conspicuous, which may impair the aesthetics of the bathroom and reduce the design, and the surroundings of the bathroom floor sheet 1 By enclosing the material like a bank with the sealing material 7, water is accumulated on the floor sheet 1 for the bathroom, drying of the water is delayed, and soot and odor may be easily generated.
If the height difference 7H2 is too small, the thickness of the corner corner portion 7d placed on the surface 1c of the bathroom floor sheet 1 becomes thin, and the end of the bathroom floor sheet 1 is rolled upward. May not be prevented.

  As shown to Fig.7 (a), it is desirable to provide the surface 7e of the sealing material 7 of the bathroom floor of this embodiment so that it may incline toward the corner | angular corner part (hem | bottom) 7c from the vertex 7f. By providing an inclination on the surface 7e, water on the bathroom floor sheet 1 can be efficiently poured along the inclination from the surface 1c toward the drainage channel 10.

Further, as shown in FIG. 7A, the surface 7e may have a substantially planar shape in a sectional view from the apex 7f to the corner corner (hem) 7c, or as shown in FIG. 7B. In addition, the shape may be a concave shape in the cross-sectional view downward direction, or may be a shape that rises in the cross-sectional view upward direction as shown in FIG.
Especially, it is preferable that it is a cross-sectional view substantially planar shape.
If the surface 7e has a shape that is recessed in the cross-sectional view, the strength of the sealing material 7 may be weakened and may be easily damaged, and the corners (hems) 7c and the vicinity thereof are thinned. Since the sealing material 7 is peeled off because it becomes easy to bend and the base surface 8a is seen through, there is a possibility of deteriorating the design.
On the other hand, if the surface 7e has a shape that rises in the cross-sectional view, the sealing material 7 is conspicuous, and there is a risk of deteriorating the beauty.

Here, FIG. 8 is a plan view of the bathroom floor of the present embodiment as viewed from the direction perpendicular to the surface of the bathroom floor sheet 1. In FIG. 8, the bathtub 11 occupies a part of the bathroom, the bathroom floor sheet 1 is laid in the remaining part, and the sealing material 7 is applied around the bathroom floor sheet 1. Further, the sealing material 7 is constructed away from the bathroom wall surface 9 and forms a drainage channel 10. The water on the bathroom floor sheet 1 flows into the drainage channel 10, flows through the drainage channel 10 along the slope provided in the bathroom, and is drained from the drainage groove 12.
As shown in FIG. 8, it is preferable that the planar shape of the bathroom floor sheet 1 used for the bathroom floor of the present embodiment is a shape in which the corners 1d of the four corners are chamfered.
If the corner 1d has a rounded shape, the corner 1d of the bathroom floor sheet 1 comes into contact with a bather's foot or a cleaning brush, so that the corner is difficult to be squeezed upward. The peeling of the floor sheet 1 can be more effectively prevented.

  Other configurations of the present embodiment are substantially the same as those of the first embodiment, and elements common to the first embodiment are denoted by common reference numerals and description thereof is omitted.

  In addition, this invention is not restricted to said embodiment, A various change and deformation | transformation are possible.

  For example, in the second embodiment described above, an example in which the bathroom floor sheet 1 covers most of the surface 8a of the base 8 with a single sheet is shown. However, the present invention is not limited thereto, and as illustrated in FIG. A plurality of floor sheets 1 may be constructed on the surface 8a of the base 8 with a certain interval so-called partially laid.

  According to such a configuration, the drainage speed can be increased by forming the drainage channel 13 between the plurality of bathroom sheets 1 constructed, and the drying speed of the bathroom floor can be further increased, thereby reducing the generation of soot and odor. Can be prevented more effectively.
